Aoa, I am planning to appear in the 2019 CSS examinations and I have selected the following subjects:
Psychology
Public administration
International relations
International law
Environmental sciences.

I am a medical student and I am planning to give BA examinations in 2018 with IR and psychology thus I don't have any experience with any of the subjects but they somehow managed to appeal to me. I need advice on whether this subject combination is good. Your help is appreciated.
